9 Claims. (01. 120-29) My present invention, in its broad aspect, has to do with copy holders for typewriters and the like, and more particularly, it is my purpose to provide a device of this general character which has adjustable means for supporting a book, bound manuscript, or other comparatively bulky subj ect matter, in proper position to be copied, with a line guide having means for initially adjusting the same, and constantly adjusting theline guide thereafter during the operation of copying, and also to provide adjustable means for supporting a sheet, or loose sheet copy'material and the like, in proper position for copying, and to provide in connection therewith means for feeding the sheet to a line guide having means for initially adjusting the position of the sheet, and constantly adjusting the same to the guide thereafter during the process of copying. Furthermore, my copy holder is constructed and arranged to support thereon a typewriter or the like, and there is provided a handily located operating key to an operating mechanism for continuously adjusting both the book guide and the sheet feed to its line guide, with means for adjusting the same to different line spaces; which key is disposed adjacent to the typewriter keyboard.

Another important object of my invention is to provide means whereby the book guide may be adjusted for different book sizes, and wherein means are provided to hold the book open with the pages extended and relatively flat and arranged at a proper angle for copying. In conjunction with the page holder, I provide unique and improved means for supporting the page at the back as it is presented for copying, and means for retaining it in a fiat position.

In connection with both the book holder and the sheet holder, and the respective line guiding means therefor, I provide means for manually effecting initial adjustments, and in connection with the means for efiecting continuous line-byline adjustment of the book line guide and making continuous line feeding adjustments of the sheet to its line guide during copying, I have provided novel and improved clutch means formed to have three positions; one position being to actuate the sheet with reference to its line guide; another to actuate the book line guide; and a neutral position when either the sheet may be adjusted or the book line guide may be adjusted manually, or initially positioned. Furthermore,

in connection with the means (including the op;

erating key or button) adjacent the typewriter keyboard for actuating the sheet with reference to its line guide and book line guide, I have provided reversing mechanism so that the direction of line feed may be reversed if desired, and the clutch device embodied therein for accomplishing these ends has three positions; one for normal line feeding operations; one for reverse feeding, and a neutral position, all this in addition to adjusting the operation of the line guiding means to lines having different spacing.

Other objects and advantages of my invention may be briefly noted as follows: (1) to provide a stand or support wherein the copy holder is arranged back of a typewriter on the stand or support, in the most convenient position to obtain a clear and unobstructed view of a sheet or book to be copied, (2) to provide the book or sheet as mounted for copying without discomfort to the operator and wherein guiding means for the lines may be actuated without inconvenience or delay; (3) to provide means for insuring smooth, effective and positive actuation of the several parts and at the same time reduce the number of operating parts to a minimum, and (4) to provide a copy holder which may be used with all conventional forms of typewriters and the like, and which will not be in the way of, nor encumber, a typewriter stand or table, and which will properly support a typewriter thereon.

With these and other objects and advantages in view, my invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the drawings wherein like characters ofreference are used to designate like or similar parts throughout the several views:

The numeral I designates astand, support-or platform which is'of asizeand shape to support a conventional typewriter (not shown) on an ordinarytypewriter-table-or desk (not shown). Adjacent to but spaced inwardly "from the rear cornersofthe supportI are vertical posts 2 which aresubstantially U-shaped in cross section, with their open faces-directed inwardly, and connecting the posts 2--is-a back plate or web--3. The base of the support I is-flanged downwardly-and outwardly-as at"4-to give a-proper footing on a table,-desk or-the like (not'shown). Attached tothe posts -2--near the topthereof, and sloping forwardly and downwardly, is a plate orsheet guide-or rest and pivotally-mounted on'and betweenthe postsistransverse line guide bar -having upwardly bent ends 1 respectively engaged andmounted on the short shafts 8-and hav- 1 ing a lever 9 to raise'and lower the same.

Sheet support. and line guide .'Journaled in'the posts 2 is a roller or platen I9, which may be rubber or composition covered .asat II. The platen Ill' has a shaft I2 on which isrnounted a fixedsleeve I3 carrying abeveled pinionI4 bearing against the outersface of the post 2 (see Figure 7) and a manual operating knob I5. Betweenithe knob I5 and the post 2 is a housing "I5, carrying a bearing I1 for the shaft and sleeve. "Pivoted on brackets I8 on posts "2 as at'l'9 are vertically extending arms 2|] having enlargedfinger engaging tabs 2| carrying pins "22 about which are compression springs 23 in deplaten I9, either :lever 21. may be operated or the finger tabs 2I pressed. 'Mounted on shafts 8 are depending arms 29 carrying a rubbersmall diameter roller 39 servingasa guide roller and engaging the sheet guide or rest 5see Figures 1 and 9. A sheet of paperisfedupwardly-between rollers I9 and 25 .andbetween roller 39 and guide plate or rest 5 beneath line guide 6.

Roller I 0 is the activeroller and is turned' by knob 15% feed the sheet in-the manner 'described. By thesemeans -asheet is-initially posipost 2.

tioned for copying; the line guide 6 disposed beneath the first line to be copied.

To feed the sheet upward line by line successively, I provide in housing I 6 a twin beveled gear clutch element, one gear 32 of which is positioned to mesh with beveled gear I4 of roller I 9 on shaft I 2. Gear 32 together with companion beveled .gear 33 on grooved sleeve 34 are keyed-as at 35 to a vertical shaft 36.journaledv as at ,3! in the housing and extending downwardly alongside of A clutch arm 38 engages grooved sleeve 34 and is held in a normal position with gear 32 -engaginggeari 4 by springs 39. The clutch arm -is--mounted on a slidable support 40 engaged by operating lever..4l to be moved into and out of engagement with gear I4.

Referring toTFigure 2, it will be noted that the lowe end of vertical shaft 36 is journaled in an elongated housing element 42 and carries a beveled gear 43, meshin with a beveled gear 44 On a horizontal shaft 45 in housing element 42 extending to the front of platform or support I. Communicating with housing element 42 at the front of platform or support I is a second housing 46 having an upward internally threaded tubular extension 41. Shaft 45 enters housing 46 and carries a'beveled gear 43. "Adapted tomesh with gear 48 are companion but reversedgears 49 and 56 on stub shaft 5| in the housing. --Each gear 49 and 59 has a grooved sleeve-52, and-areengaged by the forked ends 53 of a lever 54-pivoted on shaft-55 intermediate their ends as ati56-and to fixed pivots '51 on the housing at-their upper ends. The shaft 55 is engaged by a spring 58 to be normally urged in a direction to engage gear 49 with gear 48 as shown in Figure 4. A hand-operating lever 59 is engaged with the end of shaft 55 and is pivoted as at-69 to housing 46. A bifurcated support 6| engages the shaft55 and on the shaft between the bifurcations of support BI is'a ratchet wheel 62'engaged by a vertical rack-63 pivoted to the lower end of a rod 64 in cylindrical extension 41 and journaled in the cap 65. Cap 65 has a threaded sleeve 66 engaging the threads of extension 41. A collar 51 is pinned to rod64 and a-spring 68 engages collar 61 to normally hold the collar against the cap. The rod 64 extends through cap 65 and has a key or finger-button 69 -on the end to be engaged bythe finger to press the rod down against'the pressure of spring-'68 to move rack 63 to rotate the ratchet wheel62 to rotate shaft 55 which in turnrotates gears-49 and 59-see Figures 4, 5 and 6.

' By adjusting the cap-'65 the length of the stroke of rack 53 can be regulated and accordingly the extent of rotation of shaft 55:upon-one stroke downward of rod 64.

In operation, assuming a sheet of material to be copied is in the initial position-previously described and gears I4 and 32 are-in mesh as in Figure 8, and gears-49 andtB are in mesh as; in Figure 4, pressure on key or button 69 will rotate shafts 45 and36 through gears 43-and-44 to'the extent of the stroke of rack '63. This will rotate roller ID to move thesheet upward one line. 'If the lines of the sheet'are spaced at greateror lesser degree than the normal setting, the cap 65 is adjusted to vary the stroke of the rack to conform to the spacing of the lines. By moving lever '59 gear- 49 can be disengaged from gear'45 and gear 50 engaged with gear-45 which will reverse the feeding or rotation of roller IOand retions manual adjustments may be made, and the Book support and line guide Carried by posts 2 are slotted plates 18 having racks or tooth edges II. Mounted to slide in the slots of plates I8 are blocks 12, and journaled in the blocks is a shaft I3 carrying gears I4 in mesh with racks or toothed edges II. Fixed to blocks 12 is a book support platform I5. Mounted on the end of shaft I3 is a hand operating knob'IB having a spring 'II pressing on friction collar 18 which engages post 2, so that by turning the knob IS-see Figure l4-the shaft I3 and gears 14 are rotated to travel up and down the racks II to position the book support platform I5. Inadvertent movement of the platform is prevented by the friction collar 18. A book back support I9, having a slotted base part 88 is adjustably mounted on platform by thumb screw 8|. In order that a book (not shown) on platform 15 may be properly supported in open position with the pages reasonably flat, I provide a book clamping rod 82, having gears 83 at the ends meshing with teeth 84 in the slotted supporting arms 85 which have angular slotted extensions or ears 86 at their bottom ends engaged by pins 81 in the platform to pivotally mount said arms about said pins. There are springs 88 which normally urge the arms and rod 82 against the book. The rod 82 is adjusted on the arms by knobs 89'to properly engage a book. These knobs may be of a construction similar to knob I8 to be frictionally held against inadvertent movement.

slidably mounted on posts 2 are flanged plates 98 having racks 9I and held in place on the posts by plates 92 and screws 93-see Figures 2, 7 and 8. Each plate has a forwardly extending bracket member 94. Pivoted between the brackets is a rod 85 having bent portions 98 forming levers engaged by springs 91 to normally urge the rod to maintain a normal position. Fixed to the ends of the rod 95 are slotted arms 98 having toothed inner edges or racks 99. Adjustably supported on arms 98 is a book line guide I88, there being gears I8I meshing with racks 99 and operating knobs I82, of a type similar to knob 18. Line guide I88 is normally urged against the face of the book by springs 91 operating on rod 95. Initial adjustment of the book line guide I88 is made by turning knobs I82.

Continuous adjustment of the book line guide to designate successive lines for copying is obtained through sliding movement of racks 9| on plate 98 by means of gears I83 on shaft I84. Gears I83 mesh with racks 9| and shaft I84 is journaled in posts 2 and has a beveled gear I85 see Figure 8on the end thereof which meshes with beveled gear 33 of clutch element 3| in the second active position of the clutch element 3I to rotate gears I83 and move racks 9| to move the book line guide I88 from line to line through the instrumentality of shafts 38 and 45 and key 69 and the direct and reversing clutch and actuating mechanism in housing 48, previously described. The extent of movement line-for-line being adjusted through cap 65 as affecting the stroke of rack 83 on ratchet 82 as previously described with reference to the sheet line guidesee Figures 4, 5 and 6. It will therefore be seen that I accomplish the following purposes in connection with my book support and line guide: (1) the support platform is adjustable to accommodate different sizes of books; (2) the'book back support is adjustable; (3) adjustable means are provided for holding the book in open position and the pages thereof relatively flat; (4) my line guide is manually adjustable to an initial position, and (5) successive adjustment of the line guide is affected from an actuating mechanism adjacent the typewriter keyboard and through a common clutch and reversing mechanism with the sheet line guide.

Furthermore, since clutch 3| has a neutral position as previously described, I provide a knob I86,on shaft I84 for affecting further manual adjustment of the line guide.

, From the foregoing, it is believed that the operation and advantages of my invention will be apparent, but changes in form, size, shape, construction, arrangement, and operation may be made to meet practical requirements of practice provided such changes fall within the purview of my broad inventive concept and the scope of what is claimed.
